1st Gen ipod touch - usable?

I have a first gen ipod touch which I'd like to use (it still works). Is there any way for me to find apps that are still compatible? I don't keep any apps on my mac since my phone and ipad can download directly from the store. I know I'll have to sync with my mac. That's ok. I am just curious if there is anyway to search for compatible apps?

I have a 2nd gen Touch and its barely usable. Its really slow and crashes constantly. Restoring doesn't help, because its iOS 4.2 bogging it down. If I were you, I would just restore it to factory and use it for Safari and email. There are hardly any apps out there that still support iOS 3
